BleacherReport.com continues their series of team-by-team mock drafts, projecting the best-case, most realistic and worst-case scenarios for each team. As we move forward we'll combine these mocks in to three-team packages for easier consumption.

Truth be told, GM Scott Pioli could pick just about anyone with the fifth overall selection, and that pick almost certainly would be an upgrade over the player who played that position in 2009.

What fans need to understand however, is that the draft isn't solely about who a team can grab with their first-round pick. The draft is about leveraging each and every pick against the available talent pool, and acquiring guys in each round that can help your football team.

In this mock draft, I've put together a group of players that should all be available when the Chiefs' pick comes up in each round. Even better, six or seven of these guys could very well start for this team next season.

An average class of elite senior talent, and fears about future rookie contract limits, have pushed a huge number of juniors and redshirt sophomores into the 2010 NFL Draft mix.

Fifteen underclassmen went in the first round in 2009, tying the record shared with the 2004 draft. The 23 juniors and third-year sophomores picked in the top two rounds last April, however, set the league record.
